Measurement of the proton-antiproton total cross section at the SppS collider by a luminosity dependent method

Abstract The proton-antiproton total cross section was measured at the center-of-mass energy of s = 541 GeV at the S p pS at CERN using a luminosity dependent method. The result σtot=63.0±2.1 mb is in agreement with the luminosity independent measurement performed earlier by the UA4 Collaboration.
